IMPROVED ROTARY BELL-HEAD.

The Schedule referred to in these Letters Patent and making part of the same To all lwhom tt may concern Be it known that we, SMUEL M. FULTON and WILLIAM M. FULTON, of the city of Pittsburg, in

the county of Allegheny, and State of Pennsylvania,

y hung with au improved bell-head.

Figure 2 is a front elevation thereof.y

Figure 3 is a horizontal section of the bell-crown, in the line o r offig. 1.

Figure 4 is a vertical section, through the crown l and yoke, in the line m a of iig. 1.

In the several figures like letters of reference denote similar parts.

Our invention is designed, not only to remedy ecr- I tain defects in the hanging of bells, but also to give -a broad bearing for the crown of the bell, against the underside of the yoke, without entering it at all, and` at the same time, to aiord a more simple and ready mode of rotating the bell when it is desired to do so, and consists in the construction of an annular flanged cavity, in the crown-piece of the bell, around the vcentral hole, for` the clapper-bolt, for the receptionv of the heads of the bolts, by which the crown `of the bell is attached to the yoke.

'lo enable others skilled in the art to construct and use our improvement, weywill describe the construe# tion and operation of our bell-head.

In the drawing- A is the bell, attached to the yoke E by our iml proved device, and swinging on the trunnions t of the yoke, in the stands B B, whiclrarebolted inthe usual way'to the frame O.'

F is the bell-wheel, attached to one of the trunnions, t, of the-yoke, tor ringing the bell.

The yoke E is made inthe usual way, excepting4 that it has not any hole for the reception of the crownpiece of the bell, which is usual in devices for ro'tating bell-heads, but only holes for the passage of the main or clapper-bolt x, and of the auxiliary boltsct et a" a'.

The crown of the bell, which is the projecting portion situate centrally ou tp of the bell, by which it is attached to the yoke E, is cast with the bell, and consists of two parts, the central or innenrpart w, which surrounds the clapper-bolt x, 'and outer part s, which is concentric with the inner part w.

The outer part s may be made with the exterior shape of a frustumy of a cone inverted, so as to give abroadcr bearing against the under surface of the yoke E.

The inner part, qu, of the crown, has a circular disk, n, on top, forming a projecting ledge all around it, and the outer part s is an annulus or' ring o, pro jecting over its legs or sides, s', toward and on a level withthe disk ofthe inner part. j

By this construction, there is formed in the crown of the bell a cavity, with an annular opening narrower than the cavity, the projecting of the ring o of the outer part, andgoi` the disk u of the inner parti" contracting the cavity in the crown, and forming ledges, under which rest the heads of the T-headcd auxiliary bolts una', a, and a by which the bell is attached to the yoke, in combination with the main or clapper-bolt x. Y

By the use of T-headed bolts, the heads projecting .fromtwo opposite sides and not all around the Shank of the bolts, the head of cach such bolt may be inserted between the disk yu and ring 1 of the crown,

into the cavity, when, being turned one quarter round, the he'ad of the holt rests under the iianges formed by the disk and ring, andthus sustains thc bell, the

bolts being passed upward through the yoke E, and

secured by nuts screwed on the bolts.

Although we have described the crown of the bell as formed of separate pieces, inner and outer, and of .legs s, disk u, and ring n, yet these parts yare all cast together with the hell, and really form one piece with it. j

Also, the outer piece s of the crown, instead of having legs s s', with spaces .between them, may be in one piece, without such spaces; but it is sufficiently' strong, andV more easily cast when made as shown in the drawing, and more particularly in detail in gs. 3 and 4.

The clapper of the bell is attached in any desired way, to the lower c nd of the main or clapper-bolt x, which passes up through'the centre of the bell-head, and, oi' course, through the centre of the crownpiece w.

It also passes up through a slotted hole in the yoke E.

'lhis slot in the bolt-hole of the yoke E is made to receive a pin, p, which is passed through the clapperbolt x, and the slot and pin p prevent the turning of the clapper, when the bell is rotated, so as to change the point of stroke ofthe clapper` on the bell, the clapper being so pivoted to the bolt x as always to swing all that is necessary is to slacken the bolts x a a a, a, by loosening their nuts, when the bell may be readily turned, and it is fastened again by simply The annular flanged cavity in the crown-piece of the bell, around the central hole for the clapper-bolt, for the reception of the heads of the bolts by which the crown ofthe bell is attached to the yoke, and is thus. rendered capable of being rotated, relatively to the yoke', substantially ashereinbefore described.
